FRANK B. DUFFEY, OF HASTINGS, MIOHIGANV IMPROVEMENT IN PLASTIC COMPOUNDS FOR MAKING ORNAMENTAL ARTICLES.

Specification forming part of Letters Patent No. [68,086, dated September 28, 1875; application filed August 24, 1875.

To all whom it mag concern:

Be it known that I, FRANK B. DUFFEY, of

Hastings, in the county of Barry and State of Michigan, have invented certain Improve ments in Plastic Compounds, of which the following is a specification:

My invention consists of a plastic compound for the manufacture of ornamental and household articles, as hereinafter more fully described.

To construct my plastic compound 1 take of Paris Spanish whiting, three pounds; white lead, ground in oil, one pound; coach-varnish, six drains; Dammar varnish, six drains; Japan drier, three drams; boiled linseed-oil, ten ounces. These ingredients are to be thoroughly mixed and worked together, together with a small quantity of burnlrumber or similar pigment, to impart to the mass such shade for attaching to furniture; also picture-frames,

letters for signs, door-plates, 850., brackets, and all similar articles, it being soft and very easily worked, and when dry is very strong and tough, and does not check or crack. When finished, the articles should be coated with varnish to give them aneat appearance, though this may be omitted, if preferred.

In making picture frames, boxes, brackets,

&c., it should be secured upon a foundation or body of pasteboard; or, if the article he a large one, it may have its body formed of wood. It adheres readily to pasteboard, wood,

glass, metal, or almost any solid material, and

when thoroughly dried its tenacity is very great, thus enabling it to be readily and permanently secured to any desired object.

By properly working and mixing together different colors or shades of the compound any style or grain .of wood may be most perfectly' imitated, as may also the various veins of difterent kinds of stone.

The compound is cheap, its preparation and manipulation very simple, and the articles formed of it are strong and durable.

The proportions herein named may be varied somewhat Without materially affecting the compound.

To enable the public generally to prepare the compound, I will state that one dram is equal to two-thirds of an ordinary tea-spoonful,and that, consequently, the six drains of coach and Dammarvar-nish will be equal to four tea'spoonfuls of each, and the three drains of the Japan drier will be equal to two teaspoonfuls of the same.

Having thus described my invention, what I claim is The plastic compound for the manufacture of ornamental articles, consisting of Spanish whiting, white lead, coach-varnish, Dammar varnish, Japan drier, and linseed-oil in the proportions substantially as herein described.

FRANK B. DUFFEY.
